You need to use LDIF as specified in RFC 2849; note that there is a
specific example that shows what you're trying to accomplish:

# Modify an entry: add an additional value to the postaladdress
# attribute, completely delete the description attribute, replace
# the telephonenumber attribute with two values, and delete a specific
# value from the facsimiletelephonenumber attribute
dn: cn=Paula Jensen, ou=Product Development, dc=airius, dc=com
changetype: modify
add: postaladdress
postaladdress: 123 Anystreet $ Sunnyvale, CA $ 94086
-
delete: description
-
replace: telephonenumber
telephonenumber: +1 408 555 1234
telephonenumber: +1 408 555 5678
-
delete: facsimiletelephonenumber
facsimiletelephonenumber: +1 408 555 9876
-

In detail, look at the 'facsimiletelephonenumber' portion of the operation.
